1 '0 all whom it may concern: I

Be it known that I, JAMES C. Dawsox, a citizen of the United States, andresident of Webster Groves, county of St. Louis, and State of Missouri,have invented certain new and useful Improvements in Shiftable-SheetBinders, of which the following is a speciused in connection withthekeeping of accounts and for similar purposes. The shiftlng of the sheetsof these binders has for its purpose to distinguish those sheets uponwhich new entries have been made from other sheets in the binder. Thepresent invention has for its object to improve the construction ofbinders and sheets of this class, and particularly to provide bindersand sheets of such construction that the shifting of sheets may bepositively controlled and cannot occur accidentally.

In the accompanying drawingFigure 1 is a perspective view showing abinder and upon the flexible back 12.

The binder mechanism preferably comprises a plurality of filing members,as 13, 14 and 15. In the form of construction which is shown in thedrawing each of these filing members is composed of a pair of matingmovable prongs, as 16, 17 '18, 19 and 20, 21, forming a complete butopenable ring. When constructed in this way, that is with all of thefiling members 13, 14, 15 in the form of a complete ring or loop, it isdesirable that at least one of the rings, as 14,'be openableindependently of the others. In the arrangement illustrated all of therings are adapted for independent operation. To

this end the prongs of which each ring is' composed are mounted uponseparate .platesx as 22 and 23, 24 and 25, and 26, 27, respectively. Theplates of each pairare shown as having pivotal engagement at their meet;ing edges and as being held in such engagement by a resilient retainingplate 28; This" retaining plate embraces the several pairs oi platesbetween its two side edges and the arrangement provides that durin theoperation of any one of the rings, as; 12, the

corresponding plates, as 24, 25, arefmoved These sheets are a crturedalon one ed e to r ceive the several filing members, as 13,

1.4 and 15, and preferably these apertures are so constructed as topermit-the sheets to be shifted in the binder mechanism withoutdisengaging them from the rings 13 and 15.. To this end elongatedapertures, as 30 and 31, are provided for receiving the rings 13 and 15,espectively. As shown, the longer dimensionsof these apertures extend ina direction parallel to the adjacent edge of the sheet, whereby theshifting of the sheets is accomplished by moving them in the directionof the holding edge of the binder. The remaining. fi1ing member, as thering 14, serves to positively hold the sheets in adjusted position \Forthis purpose two filing apertures, as\3 2, 33, are provided in thesheets for receiving the ring 14. Each of the apertures 32, 33 is ofsuch restricted size as to prevent any movement of the sheets in thedirection of the holding edge of the binder when the ring 14 is engagedwith either of such apertures. Furthermore, the apertures 32, 33 arenon-connecting. The sheets must accordingly be disengaged fromthe-filing member 14 to allow them to be shifted. When the filing member14 takes the form of a complete ring, as shown, this can only beaccomplished by opening the ring. It is for this purpose that the bindermechanism is "most desirably so constructed as to permit the ring 14being opened independently of the other rings, as 13 and 15.

Vfhen'the parts, as 18, 19, of the ring 14 have a swinging movement foropening'and closing the ring, the apertures 32, 33, are elongated in adirection transverse to the holding edge of the binder to permit suchmovement of the parts of the ring when engaged with the sheet.

29 will preferably be arranged 'upon the rings 13, 14, 15, with the ring14fengaging' the same aperture, as 32, of all of the sheets. 5 Usuallythe sheets will be arranged between suitable guide or index leaves, as34. When. a new entry has been made on any one of the sheets 29, thering 14 will be opened and the sheet disengaged from the ring 14 andshifted on the rings .13, 15, to a position in which one of its edgesprojects beyond the corresponding edges of the remaining sheets, asappears at35, Fig. 1. The shifted sheetis then filed upon oneof the ofthe ring 14 in its new position, and the ring closed. In the newposition of the sheet the ring 1.4 is engaged with the other one, as 33,of the two apertures provided for receiving it and serves to positivelyhold original position. The new position of the sheet serves todifierentiate it from other sheets upon which new entries have not beenmade, whereby reference to the new entry to the new entry is no longerrequired, as when the new entries have been posted at the close of adayls" business, the ring 14 will bevopened. and the shifted sheet re;

turned to its original position.
